Anyone know about Samsung EMMC chips?

I need to know how to get a user dump from a Samsung SIII eMMC chip. The board is cracked and useless. No power to the chip. I have seen some Korean videos of reading the user partition off the chips, but I'm not sure what exactly they're using. There are some adapters I've seen that are supposed to have adapters for Samsung chips, but haven't seen anything that mentions the L710. And then I'd need a "box" that all seem to be over $100. A little excessive for one-time use.. Are there any services out there that might be able to grab this data?
